Glossary of LEGO Terms

We get it, LEGO enthusiasts have their own language (most of which is based on acronyms) and we can be very hard to talk to. Well there is good news, Charm City LUG has compiled a list of some of the common LEGO terms you will hear at our meetings and LEGO fan events around the country. Check out the definitions below, and join us for an upcoming meeting to demonstrate your LEGO lingo!

*Please note, while the definitions on this page are often recognized within the AFOL community, this resource page is available in jest. Don’t take it anything to seriously, we are just having fun.
